function in the config editor to one that checks where ALL variables marked
with year=-1 exist for FAIRYEAR. If it doesn't, it creates them. This

- On installation
- On rollover
- Whenever the database is updated

will be automatically updated for the current year with the default value.
(no more going into the variable editor to make sure the copy is done).
